hello,
i was trying to use more than one input with minim and found out that you cannot specify the soundcard you want to use or which input of the sound card you want to use.
AudioOutput output = minim.getLineOut(Minim.STEREO, Config.BUFFERSIZE,Config.SAMPLERATE);
however Minin.STEREO == 2 and Minim.MONO=1, you could try to hack minim a bit and pass 8 as the number of channels parameters.
any how i'd interested to hear about your findings here.
